PC

Polycarbonate
High-temp · High-strength

Polycarbonate is what we reach for when a part runs hot and still has to carry load. Heat deflection of 114 °C at 0.45 MPa, and the highest impact strength in our FDM lineup.

Strengths
& uses

Where the temperature goes up, the loads get serious, or both at the same time.

Strengths
  • Heat deflection 114 °C at 0.45 MPa — 99 °C under a 1.8 MPa load
  • High strength and stiffness
  • Charpy impact 21.28 kJ/m² — the highest of our FDM materials
  • Dimensionally stable under sustained heat and load
Common applications
  • High-temp brackets
  • Under-hood automotive
  • Industrial heat shields
  • Structural prototypes
